SQL：从嵌套表oid中选择

Question

我尝试从嵌套表中进行选择但显示错误消息＆＃34; ORA-00933：SQL命令未正确结束＆＃34; 这是选择的要求

select b.NomPlayer from  table (select t.players from Team t where t.IdTeam=1) as p;

这是我创建player_type和team_type

的代码

CREATE OR REPLACE TYPE Player_Type AS OBJECT ( Num_Licence NUMBER, NomPlayer VARCHAR2(30)) ;
CREATE TYPE PlayersNT AS TABLE OF ref Player_Type ;
CREATE TYPE Team_Type AS OBJECT ( IdTeam NUMBER, TeamName VARCHAR2(30), Players PlayersNT ) ;
CREATE TABLE Player OF Player_Type ;
CREATE TABLE Team OF Team_Type
NESTED TABLE Players STORE AS PlayersTab ;

Answer 1

删除AS子句中的FROM。与其他数据库不同，Oracle仅允许AS子句中的SELECT。

select * from table(select t.players from Team t where t.IdTeam=1) p;
